In 2012 there were 33 Senate seats up for grabs, and the cost to a candidate of winning one averaged $10.5 million, if the popular estimates of what winning candidates raised are to be believed. That's something like $700 million total spent by both the winners and losers.
For all 435 House seats the candidates spent something like $1.5 billion, with $1.7 million spent on average by each winner.
With $6 billion total spent on the 2012 Congressional election from all sources thanks to additional PAC spending courtesy of a US Supreme Court ruling, the candidates themselves therefore spent at most $2.2 billion while outside interests spent an additional $3.8 billion to elect both "your" representative and "your" Senator. No wonder you like them so much.
The five most expensive races alone in 2012 were for Senate seats, and cost from all sources in excess of $376 million, $142 million of which came from "outside" sources, 38% of the total. Assuming that $700 million was spent by all 33 Senate candidates themselves in 2012, and adding an additional 38% from outside sources, that would put the cost of the 2012 Senate election from all sources close to $1 billion for just the 33 seats. For the whole lot of 100 Senators, then, we are in reality talking $3 billion for the whole Senate, plus the $5 billion for the whole House in that snapshot of time in 2012, for a total of $8 billion.
That makes your Senator a $30 million target, while your representative is a paltry $11.5 million one by comparison.
You could fix 72% of what's wrong with our politics in this country in an instant by repealing the popular election of Senators.
Just undo it.
